2 Claim.

This invention relates to lint collectors for textile machines.

In the manufacture of textiles where fibers are spun to produce yarns or threads and the yarns or threads pass through various operations at high velocity, a great amount of lint, consisting of fibers of extremely short length, is thrown from the yarns or threads into the surrounding atmosphere. This lint collects upon the machines interfering at times with their operation, and upon the employees, increasing the hazard to health, and upon the walls and floor, increasing the fire hazard.

The lint which settles upon the floor, walls, and machines, is contaminated with dust, decreasing its value.

The present invention aims to reduce the amount of lint in the air surrounding the machine and to provide for its collection.

The principal objects of the invention are to prevent contamination of the air, to promote the health of the employees, to reduce the cost of collecting the lint, and to reduce the fire hazard.

Other objects will appear from the following description and the accompanying drawings.

Of the drawings:

Fig. 1 is a plan view, partly broken away and partly in section, of the lint collecting device in its preferred form as applied to a textile machine.

Fig. 2 is a side elevation of the same, parts being broken away and parts shown in section, part of the textile machine being shown conventionally and part broken away.

Fig. 3 is a cross-sectional view of the same taken on line 3-3 of Fig. 2, parts oi the machine being broken away.

Fig. 4 is a side elevation of the lint collector taken from the left of Fig. 3 to show the cleanout doors, parts being broken away.

Referring to the drawings, which, by way of example, illustrate the preferred embodiment of the invention as applied to a Barber Coleman rewinding or spooling machine, the frame of the machine comprises a series of rectangular frame castings I which support the mechanism. In the rewinding machine referred to, cops ll, l2, of yarn or thread are placed on spindles in pockets l3 along the side of the device and are rewound at H in a cheese. One cheese is made up from a number of successive cops and a carriage (not shown) travels continuously on a track (not shown) around the machine and comprises an automatic knot tying device which splices the yarns or threads end to end. The high speed at which the rewinding machine operates causes a large amount of lint to be thrown from the thread or yarn. This lint collects upon the knotter necessltating frequent cleaning thereof, and fills the surrounding air with lint. 5

In order to provide a convenient compartment for collecting the lint according to the invention, I enclose the space occupied by the frames III by fastening side walls l5 and I6 and end walls l1, l8 thereabout. Hinged clean-out doors l9, l9, 19" are provided along one side of the compartment to cover clean out openings 20, 20', 20". An inclined partition 2 I, or wire screen is fixed to the side walls with its lower margin below the doors l9, l9, l9" and its upper margin above a series of openings 22, 22a, 22b, 22c, 22d, formed through the opposite wall It.

To cause the atmospheric air to be drawn toward the center of the rewinding machine and downwardly through the screen partition 2|, as indicated by the arrows in Fig. 3, and thereby to cause the lint to be collected within the machine upon the screen 2|, a blower 23, driven by any suitable source of power, such as the electric motor 24, is mounted at the end of the'machine and its suction 'end is connected by a pipe 25 to a duct 26 built along the outside of wall It and connecting with the openings 22, 22a, 22b, 22c, and 22d.

The openings are graduated in area and are progressively larger as their distance from the blower is greater in order to equalize the flow of air through different positions along the machine.

In order to provide for cleaningthe knotter and its carriage, the discharge pipe 21 is arranged to discharge its air angularly upward and away from the rewinding device across the path travelled by the carriage as it passes the end of the machine.

In operation, the air from the room is drawn in through the rewlnding devices, carrying the lint inwardly and depositing it upon the screen 21 as the air is drawn therethrough. From the screen, the lint is readily removed at intervals through the doors l9. As the lint does not pass through the duct 26 or the blower, no accumulation of lint takes place in these parts to restrict their operation or cause fire hazards. The air discharged from the blower keeps the knotter in. clean condition.

While the invention has been shown as applied to a rewinder it is apparent that it may be used for removing lint from other textile machines,

such for example as re-spoolers, clubbers, winders, creels, and weaving and knitting machines.

I claim:

1. A textile machine of the rewinding type, in which lint is generated in the operation of rewinding, said machine comprising an upright frame structure having a central space extending vertically from the zone of lint generation downward to the bottom of the machine, a casing at the sides of said structure, said casing being provided with openings in the lower portion thereof, a conduit extending along said casing in communication with said openings, suction producing means in communication with the conduit for producing an induced draft vertically downward through said machine and into and through said conduit, filter means in the lower portion of said casing for separating lint from the air stream before the latter enters the conduit from said casing, and means at the lower portion of the casing to permit access to the filter means for removing lint accumulations therefrom.

2. A textile machine of the rewinding type, in

which lint is generated in the operation of rewinding, said machine comprising an upright frame structure having a central space extending vertically from the zone of lint generation downward to the bottom of the machine, a casing at the sides of said structure, said casing being provided with openings in the lower portion thereof, a conduit extending along said casing in communication with said openings, suction producing means in communication with the conduit for producing an induced draft vertically downward through said machine and into and through said conduit, means in the lower portion of said casing for separating lint from the air stream, said lastmentioned means comprising a filter structure disposed obliquely across the bottom portion of said casing in such arrangement as to filter lint from the air stream before the latter enters said conduit from said casing, and means at the lower portion of the casing to permit access to said filter structure for removing lint accumulations therefrom.
